Don't know if anyone else had noticed, but the DC/Baltimore Board recently only went back to about May 2001, and our first 3000 or so posts were missing. I inquired on the Site Talk Board, and Jim Leff warned that it was probably the result of a server crash that had wiped out the posts forever.
But whadda ya know?: Bob Okumura has managed to resurrect "most of the backlog," and if you now check the Board you'll see that it once more goes back to the "beginning" (i.e., July 1997). Major thanks to Bob the Restorer!
